The Incredible Return-a-Ball (3x3)

:

Marcus sees a commercial on his laptop for Francine's latest invention, the Return-a-ball, which is supposed to come right back to you when you throw it. He can't resist buying one but quickly discovers that it doesn't work and it's just a regular ball. The rest of the Electric Company pitches in to help Marcus prove that Francine faked her commercial so he can get his money back.
